Dynamics GP - SSRS - Historical Aged Trial Balance Report does not Match GP - Customers are missing

This is happening because the default filters used when you leave them blank in SSRS are "þþþþþþþþþþþþþþþ" in the seeRMHATBssrsWrapper stored procedure.

The stored procedure should be updated, and  "þþþþþþþþþþþþþþþ" replaced with "zzzzzzzzzzzzzzz"
